Thanks Jakobi, in the meantime I checked the parts book and the drawing is, as you probably expected, correct. The ridge points to the wheel.
Talked to a German dealer and he said the bikes come delivered with front wheel not installed and the left, only the left, bushing is strapped to the wheel with a zip tie. Obviously the assemblers just dont know and install it the wrong way.
No big deal, I was just wondering. So all clear now
